Carrier Codes

The Carrier Codes table allows you to enter a maximum of five carrier code prefixes.
• You can define up to five carrier codes.
• Entries may be predefined for a specific country profile, but you can remove these defaults.
• Each entry consists of an equal access identifier code prefix (one to six digits) and a carrier
identification code length (one digit, 1 to 9).
• Each entry is identified by the prefix digits themselves.
