Enter the number and see whether it is mobile, landline, toll-free or premium.
The national numbering plan explains a lot: 2xx is landline, 69x mobile, 800 toll-free, 801 and 806 shared cost, 901 and 909 premium. Five-digit numbers are short service codes.
The tool strips spaces and dashes, recognises a country prefix and returns the category and, for landlines, a known area. It does not identify a caller: that is a different service and a different data question.
For 901 and 909 the charge is not capped by regulation; ask your provider before calling. Do not call back unknown numbers from abroad.
210 123 4567: landline, Athens area. 6901234567: mobile. 9011234567: premium.
Not here. Caller identification is another service and needs data the tool does not hold.
The current cap was not confirmed; check with your provider.

The tool explains the number class from the national numbering plan; it gives no caller identity. The area codes shown are a sample, not the whole country. The 901/909 price and the 806 cap were not confirmed.
