Splits are listed in order of the start date of permissive dialing. Also, check the site for any possible additional PLs since then as well as any News Releases at the site. The extent and timeliness of information may vary by site. TRA is planning to include data in its TPM product to reflect Mexican re-numbering . Existing numbering information will remain in the TPM as well through the end of the permissive dialing period.
Actual records changed are a small percentage of the total number of records.
For example, alpha OCNs have been introduced into the TPM, primarily for NPA 500 and 900 NPAs. Please call the TRA Customer Service Center if you have any questions regarding this. The LATA concept as instituted by the U.S. Department of Justice in 1984 technically does not apply to Canada. A past effort that associated Canadian data with a certain set of 800-series LATA codes was becoming difficult to manage and explain. This fee is due the RAO Administrator for the assignment of each non-hosted RAO Code.
