Grapevine-Colleyville ISD is making some changes to the School Messenger automated calling system. Currently, when GCISD sends a phone message, it uses the main district line. Moving forward, calls will come from the following number: 866-264-0350. By using this toll-free number, call recipients will be able to place a call back to this number to hear any missed calls, which is an added benefit to all families. Please save this number to your contacts as a reminder that these calls are coming from GCISD.
