Two new User Group/Platform classifications for N were introduced in 2005 in the National Destination Code (NDC) for the implementation of Speednet's CDMA mobile cellular network:
The PSTN (Public Switched Telephone Network) with “0” as second digit, and mobile numbers with “0”or “2” as second digit, are restricted from accepting collect calls.
N = User Group/Platform classification/Identification for the respective service providers, where N = 0 – 9
For example:
0 = PrePay (e.g. Prepaid/Pay phone for a specified service provider)
1 = Mobile (e.g. Mobile for a specific service provider)
2 = PSTN (e.g. Public Switched Telecommunication Network for a specific service provider)
3 = Reserved
4 = Reserved
5 = Reserved
6 = Reserved
7 = Reserved
8 = Reserved
9 = Reserved
Y = First digit of a virtual five-digit subscriber number and/or first digit of present five-digit subscriber numbers – (0 – 9)
XXXX = Subscriber numbers (0000 – 9999)
Potential numbers with 0000 and 9999 will be reserved
Assigned numbers will start from 00010
Assigned numbers will stop at 99998
Subscribers/Customers will be required to dial seven (7) digits for all local calls whether within the same area or district or to another area or district.
Number digit “1” identifies Belize Telecommunication Ltd.
Mobile cellular service by another service provider for same subscriber will be 654 9076.
Number digit “5” identifies the other service provider.
The choice of dialling the middle digit “1” or middle digit “5” will be that of the consumer and would be based on service cost and interconnection arrangements.
As of early 1996, AT&T and other reliable sources indicated that Belize had recently changed its switching arrangements for incoming international calls so that all locations in the country required an area code to be dialed.
The area codes were still of varying length, followed by numbers of a more fixed length than before. Belize City now required an area code of 2 in order to be dialed, while the digit 0 was deleted from all other area codes when calling from outside the country.
Belize City was 2, Caye Caulker was 22, Ladyville was 25, San Pedro was 26, Burrell Boom was 28, and other outlying areas around Belize City were 21. Presumably, no Belize City number would begin with 1, 2, 5, 6 or 8 in order to avoid confusion in the switch (e.g. 28-8012 could be mistaken as 2-88012).
Prior to this change, and starting at least no later than 1980, Belize City was dialed as +501 then the local five digit number. Other locations were dialed as +501, then an area code starting with 0, then the local number. The arrangement indicated that incoming international calls reached the Belize City exchange, from which a further call was dialed as if the international caller was in Belize City.
The telephone network was developed during the late 1960s and 1970s with installation of modern exchanges to replace older networks, and to tie them together into a long-distance network using area codes. Neither the local numbers nor the area codes were of standard length, though larger towns tended to have a single digit after the 0.
Rural areas outside of a town usually had a separate area code, longer than that of the town, but beginning with the same digit.
For example, Orange Walk Town was 03, but its suburbs and outlying area was 031; no Orange Walk telephone number would begin with 1.
