Narrative:

While being vectored by atlanta approach into atl, we were given numerous vectors, crossing restrs, and altitude assignments. We complied with all clrncs. We had no communication problems, although it was a busy day with heavy traffic. We were later cleared for a visual approach and landed uneventfully. While taxiing to the gate, our dispatcher told us to call ATC. The captain called ATC. Apparently, the controller thought, or had some confusion over various aircraft call signs. We were air carrier X xyz and there was also air carrier X yxz flying at the same time. The controller did not say we did anything wrong, just wanted to ask the captain about if we had been confused.
