    GP surgeries in the 01436 area

This is the number the organisation publishes. Many GP surgeries, hospitals, pharmacies and schools call out from a different number or with their number withheld, so a call from this number is likely to be from them, but it is not certain.

Scammers can make a call show any number, including a real surgery's, hospital's or school's. If a caller asks for bank details, a password, a code sent to your phone or a payment, hang up. Then call the organisation back on a number you have found yourself, such as on its own website or a letter from it.

What the provider and number type mean

Numbers starting 01 and 02 are geographic numbers. The first digits are the area code, which is linked to a place in the UK. Ofcom allows some numbers to be used outside their area, so the person or business may be somewhere else. 01436 is the area code for Helensburgh.

Ofcom allocates phone numbers to communications providers in blocks. The provider shown is the one Ofcom allocated this block to. It is not the person or business that called you, and the number may since have moved to a different network, because people can usually keep their number when they switch provider. Ofcom does not hold information about individual numbers.

Calls to 01 and 02 numbers are usually included in landline and mobile call allowances. Outside an allowance, the price depends on your provider and tariff, so check with your provider.
