Electronic pitch-calling rules by governing body

How to use this guide

Baseball and softball are different rulebooks even when the organization shares a name. NCAA softball Rule 5.9.9 is not NCAA baseball Rule 5-16. USSSA fastpitch Rule 2, Section 13 is not USSSA baseball By-Law 7.01.M. Quote the sport you play.

A travel team’s weekday league and Saturday tournament often use different rulebooks. Alliance national events, for example, start from NFHS softball and then add current NCAA 5.9.9 for digital communication. The rules for that event control, even if your team is sanctioned by a different body.

Three questions separate the rulebooks. Who may wear a receiver? Is live audio treated differently from a stored message or a display? Does the rulebook care whether the transmitter is a dedicated device or an app on a phone or watch?

At a glance

The table is a map, not a substitute for the quoted sections below. “Stored signal” means a pre-recorded message, code, or display. “Live audio” means a coach talking into a microphone in real time.

Triple Crown and Premier Girls Fastpitch publish their own rules and, in both cases, different pages do not match. Those are in the tournament section, not in this table.

College

NCAA softball — Rules 5.9.8 and 5.9.9

The 2026–27 NCAA Softball Rules Book puts transmitting hardware in 5.9.8 and the one-way exception in 5.9.9. One-way devices on offense as well as defense, and transmission from the coaches’ boxes, took effect for the 2026 season.

Team personnel, including players, are prohibited from carrying or wearing any device capable of transmitting information while on the field (e.g., cell phone, smart watch). … Exception: See Rule 5.9.9.

NCAA Softball Rules Book, Rule 5.9.8.

An exclusively one-way electronic communication device from the dugout or the coaches’ boxes for the purpose of relaying the pitch or play call is permitted on defense and offense. The use of an in-ear communication device shall be limited to the defensive position of the catcher.

NCAA Softball Rules Book, Rule 5.9.9. The 2026 rules-change listing used the same in-ear limit and added that in-ear/hat/helmet audio remains limited to catchers on defense.

Approved Ruling 5-21: a coach or player wearing a smart watch onto the field is illegal except for the 5.9.9 one-way path. Approved Ruling 5-23: a coach may not download an app onto a cell phone, tablet, or smart watch “instead of the device supplied by the manufacturer” to relay signals. February and March 2026 interpretations add that coaches may wear the same in-ear one-way device as the catcher in the dugout, and may not wear that device on the field; two-way phones, iPads, and tablets may not be used to send digital signals from a team area or a coach’s box.

NCAA baseball — Rule 5-16 (formerly 5-2-f)

College baseball allowed an exclusively one-way device from the dugout to the field, with in-ear audio limited to the catcher, as a 2021–22 rules change. The 2023–24 interpretations then split stored signals from live audio:

The use of exclusively one-way electronic communication devices that transmit pre-recorded message(s) or signals for the purpose of relaying the pitch or play call from the dugout to the field (to the pitcher or other defensive or offensive players) is permitted. The use of an in-ear communication device with direct or live audio remains restricted to the defensive position of catcher.

NCAA Baseball Playing Rules Interpretations, October 2, 2023 (then numbered 5-2-f Note 1). The rationale says digital one-way devices such as a wrist device or a device that transmits a pre-recorded audio message meet the intent of the rule.

Effective with the 2025 season, the Playing Rules Oversight Panel expanded who may initiate that one-way path. NCAA’s August 8, 2024, release: “a player on the field or coaches in the third base or first base boxes can initiate one-way communication to relay signals to offensive or defensive players.” Previously the device had to originate from the dugout. The 2025–26 rulebook recodes the article as 5-16. The 2025–26 interpretations add that a first baseman may wear an earpiece to hear a pre-recorded pitch or play call; “Direct oral communication is only allowed to the catcher.”

Other electronic devices used during the contest — the August 2024 release names tablets as an example — result in ejection of the violator and the head coach, plus a one-game suspension for the violator, with no warning. A March 19, 2024, dugout-technology reminder (still numbered 5-2-f) listed smart watches among devices that may not collect, send, or receive data during the game, except the allowed one-way pitch/play device.

NAIA and NJCAA

NAIA softball uses the NCAA Softball Case Book (including A.R. 5-21, 5-22, and 5-23) and the 2026–27 NCAA softball rules-changes PDF. Until NAIA publishes its own modification, treat NAIA softball electronic communication as NCAA 5.9.9. For NAIA baseball, confirm with NAIA — they have not published a separate electronic-communication rule.

NJCAA has long used NCAA baseball and softball playing rules, with tournament exceptions for things like roster limits and run rules. Confirm the current NJCAA Sports Procedures Chart for any exception that applies to your event.

High school

NFHS baseball and softball both move, for 2027, from catcher-only to pitcher-and-catcher as permitted receivers. Baseball 1-6-2 is still “for the purpose of calling pitches.” Softball 1-9-6 Exception (renumbered from 1-8-6 in 2025) is broader in its rationale: “defensive strategy and game management information.” Neither sport authorizes receivers on the rest of the defense, two-way talk, use on offense, or a coach operating the device outside the dugout/bench area. The full quotations, 2024/2025 history, and source list are in NFHS 2027: Pitchers can receive the call.

Softball interpretations treat legality as a question of one-way use (2025 Situation 5). Baseball’s 2024 Situation 6 treated two-way capability as illegal even if muted. Do not copy one sport onto the other. Check your state association rather than a national list: baseball 1-6-3 Note 2 says states may add their own policies on electronic devices.

USA Softball

The 2025 USA Softball rulebook, Rule 4, Section 7C, is the amateur-softball change. It is not written as a catcher-only rule.

An exclusively one-way electronic communication device to relay signals to the offense.

Rule 4-7C.1.B (what a base coach may have in the box).

An exclusively one-way electronic communication device may be used by the defense to relay the pitch or play call from the dugout.

Rule 4-7C.5. Effect: if a two-way communication device is used, disqualification or ejection after a warning. 4-7C.1.C separately bars two-way devices, “to include cell phones, pagers, etc.,” on the playing field.

The January 2025 plays-and-clarifications document: a coach using a microphone to the batter while the batter also has a microphone is illegal; “the communication must be one-way only.” The comments on the rules add that an exclusively one-way device “may be used by the defense or offense to relay the pitch or play call from the dugout or field.” That is broader than catcher-only. It does not say every fielder may wear a receiver.

USA Softball announced an exclusive commercial partnership with PitchCom in June 2025. A partnership is not a playing rule. 4-7C does not name a required brand.

USSSA

Fastpitch — Rule 2, Section 13

A coach may utilize exclusively one-way electronic communication devices from the dugout/bench area only (when on defense) and from the dugout/bench area or the coach’s box (when on offense) for the purpose of relaying signals to his/her players. The device/system must be worn as designed by the manufacturer and must be commercially available to the public for purchase (customized systems and devices are prohibited). No two-way communication devices, such as cell phones, pagers, walkie talkies, etc are allowed to be worn or carried onto the playing field.

USSSA Fastpitch Rules, Rule 2, Section 13 (added among the 2025 changes). First offense: team warning and removal of the illegal devices. Second: head-coach ejection and loss of the right to use the equipment for the game. The two-way examples in that sentence do not include the word smartwatch.

Baseball — By-Law 7.01.M

The use of one way Electronic Signaling devices are permitted to be worn by all players.

2026 USSSA Baseball National By-Laws, 7.01.M. That is not a catcher-only rule. A USSSA All-American Games FAQ separately says one-way devices are legal for all age groups and “An Apple Watch is two (2) way!” That FAQ is event language, not the national by-law.

Weekend tournaments

These organizations are not a substitute NFHS or NCAA. They publish event rules on top of a base rulebook. Read the rules for the event you entered.

Perfect Game (baseball)

Multiple 2026 Perfect Game tournament pages use this heading: “Electronic Communication Devices: Adoption of NCAA Pitchcom Protocols,” followed by:

The use of exclusively one-way electronic communication devices that transmit pre-recorded message(s) or signals for the purpose of relaying the pitch or play call from the dugout to the field (to the pitcher or other defensive or offensive players) is permitted. The use of an in-ear communication device with direct or live audio remains restricted to the defensive position of catcher.

Same split as the October 2023 NCAA baseball interpretation. Perfect Game publishes this in tournament rules, not as a single national rulebook — check the event you entered. Those rules do not ban smartwatches by name.

Alliance Fastpitch national events

Alliance’s 2026 modifications PDF for AFCS, AFON, AFRC, and national qualifying events starts from NFHS and then states that all digital communication rules follow current NCAA rules, which may be used on offense and defense. It quotes NCAA 5.9.9 in full. Member-league or local Alliance play is not automatically the national-event rule. A 2024 Alliance announcement described a dugout-only version of the rule; the 2026 PDF is the later document for those named events.

Triple Crown

Triple Crown’s own fastpitch rules page says it is not a sanctioning body and follows NFHS softball with listed modifications. Its communication page:

All defensive and offensive players may have digital one-way communication from the dugout, the use of a smart watch (ex: IOS or Android) is illegal and subject to the penalty listed below. Audio one way communication can go from the dugout to the catcher ONLY.

triplecrownfastpitch.com/communication-rules. GoRout is named as a preferred partner on that page; preferred is not exclusive, and is not an NFHS rule.

The Triple Crown Fastpitch World Series rules page uses a narrower sentence: digital one-way for defensive players, and “ALL COMMUNICATION IS FOR DEFENSE ONLY AND CANNOT BE USED ON OFFENSE.” Do not assume the general page and the World Series page are the same rule. Triple Crown baseball’s communication page says one-way devices may be used by every player on defense and offense and points to tournament rules for detail.

Premier Girls Fastpitch

PGF states that its events use NFHS rules with exceptions, then prints a “Rule 5.9.9” block. One published paragraph says one-way devices are only permitted on defense, digital wristbands may be worn by any defender, and in-ear/hat/helmet audio is catcher-only. A later numbered list on the same page says the devices “Will be allowed to be used by offensive/defensive players.” Those two sentences do not match. Use the rules for that PGF event rather than guessing which line controls.

Little League

For 2025, Little League amended Rule 3.17 in both baseball and softball:

…permits a coach or manager to use one-way communication to the catcher while the team is on defense for the purpose of calling pitches. However, a manager or coach is prohibited from using the device to communicate with any other team member while on defense or any team member (including a manager or coach) while on offense, and a manager or coach shall not use the device outside the dugout/bench area.

Little League 2025 rule-and-regulation announcement. The 2026 significant updates add that a reasonable amount of time must be provided to correct a malfunctioning one-way communication device.

Other sanctioning bodies

AAU, AFA, USFA, USA Elite Select, NSA, PONY, and NAFA are not quoted here. Those events often follow NFHS or USSSA; confirm with the tournament rather than assuming a national table. We also do not keep a state-by-state NFHS adoption list — ask the state association.

None of the rulebooks quoted above names a required manufacturer. NCAA softball A.R. 5-23 requires a manufacturer-supplied one-way transmitter rather than an app on a phone, tablet, or smart watch. USA Softball’s PitchCom announcement and Triple Crown’s GoRout preference are commercial partnerships, not playing rules.

Common questions

What this means if you buy hardware

Almost every rulebook in this matrix requires the path to be one-way: coach to player, and players cannot talk back. Several college and tournament texts then split live audio (catcher) from a stored signal or display (often a wider set of players). High school NFHS 2027 still limits electronic receivers to the pitcher and catcher.

PerfectCall Varsity is built for those rules: a dedicated one-way radio from the coach tablet to player-worn receivers, with no return path from the field. That is the manufacturer-supplied transmitter NCAA softball A.R. 5-23 describes — not a phone app, not a smartwatch, not two-way talk. Programs use it in college, high school, and travel play under the rulebooks quoted above.
