Quick note: (43 years in the telephone business, GTE, CONTINENTAL, CONTRACTING). Codetel is owned by GTE, Tricom I don't know, and the first three digits of a phone number (ie: 334-xxxx) are established in the telephone central office. They have so much equipment dedicated to each area and it starts with (like) 301 a prfix and then 0001 to 9999 and then 302 prefix and then 0001 to 9999, easy????? They get 9999 numbers for one prefix and no more.. NEW PREFIX, 303 AND SO ON. The office serves 25000 homes and business's SO 3 DIFFERENT PREFIXES..My number is 879-6638 so i'm the 6637th number with the prefix 879, GOT IT??? Codetel probably has to furnish so many prefixes and access to their lines to serve the subscribers of Tricom. Thats the way it works here in US, will look into this and get back to all you good people. J.(Jim), have a good day.
