Abstract
A method and system include obtaining at a first time a first image of a database having number portability records for each telephone number which has been ported between service providers. The first image is indicative of the LNP records in the database at the first time. At a second time a second image of the database is obtained. The second image is indicative of the records in the database at the second time. The first and second images are compared to determine migration of ported telephone numbers.
