It's the main number, 0845 7740740 (geographical number 01752 381222)
It has the network announcement "The number you have dialled has not been recognised".
There is a thread with numbers on for customer services
here.
The 01752 381222 looks like it could be a switchboard number to me. I've Googled it and got nothing!
Going by the numbers, I gather Royal Mail head office is in Plymouth. Other numbers listed on here are 01752 387xxx.
