# BudgetSMS, top-up, Pay per use, GET /np/: Phone validation API

> A number portability (NP) lookup returns the network a mobile number currently belongs to: the actual MCC and MNC, also for subscribers who ported their number to another operator. It does not check whether the handset is switched on or reachable, for that, use the HLR lookup. An NP lookup is cheaper than an HLR lookup and is the right choice for routing, cleaning lists and detecting ported numbers.
