Why are GMRS call signs so long? My ham 2x2 call sign is only five digits I’m applying for some vanity 1x2 and 2x1 call signs but they are hard to get. GMRS is seven digits.
Follows the standard convention of call signs in ULS. GMRS, LMR and public safety all use the same call format. The amateur radio service is the only exception to this rule.
