Procedure
We were departing from [the] gate. We contacted Ramp Control for push clearance telling them; Aircraft X; ready to push gate X.Ramp responded Aircraft X; cleared to push gate X tail north; call me after push. We replied Aircraft X; cleared to push gate X tail north call after push.In the past sometimes [Ramp] tells us to call Ground for push clearance after first contacting Ramp for push clearance. In this case Ramp did not and so it appeared Ramp was controlling the area around our gate today. We pushed back tail north from [gate] X; without event or any nearby traffic on the ground. After engine start and control check; we called ramp back telling them we were ready for taxi. The Ramp Controller responded in a grumpy tone claiming that we called for push from gate X; and gate Y we needed to contact ground for push clearance. He told us to contact Ground. We responded that we did call Ramp for push back from gate X. We contacted Ground for taxi. Ground gave us taxi instructions to RWY XXL for departure. We read back our taxi instructions and asked the Ground Controller about what Ramp had said about our push back after we pushed. I indicated that we called and were cleared for push from X; but Ramp later seemed confused and thought it was Y. Ground said that normally that gate needs us to call ground for push; but not to worry about it. The rest of the flight continued without incident.Factors: I believe that since our flight number was XXXX perhaps the ramp controller thought we were at gate Y; even though we called X and he responded cleared to push X.Suggestions: There is no note on the company 10-7 page about gate X at the terminal needing push clearance from both Ramp and Ground Control. If there was a note for the departure briefing that mentions Ground needs to be called as well as Ramp for push clearance from [gate] X; this would help avoid this in the future.
EMB-170 Captain reported a communications breakdown between flight crew and Ramp Control regarding pushback clearance.
