Ofcom reserves 034 and 037 ranges for migration from matching 084 and 087 numbers. A familiar 0345 number can still be spoofed on an incoming call.
How much does it cost to call?
03 calls cost no more than 01 or 02 calls and must be included in bundled minutes on the same basis. They are not automatically free outside your allowance.
These are UK call-cost rules, not a quote for your individual plan. Check your provider’s tariff and any roaming terms before calling.

Allocation records identify number blocks, not private subscribers. Porting and caller ID spoofing mean the prefix cannot prove the current network, caller’s identity or physical location.
