Which Country Uses Area Code +0974?

The country which uses the dialling code 974 is Qatar, a small country along the northeast coast of the Arabian peninsular.

If you are calling from the UK, the code you will need is 00974. If you are calling from Qatar to the UK, the code is 0044. Remember Qatar is 3 hours ahead of the UK. The dialling tone is identical.

What if I'm Calling from the USA or Canada?

If you're phoning Qatar from either of these two countries, you will need to dial 011 974, then the rest of the phone number. 

Qatari phone numbers should all be 8 digits in length. To call the USA or Canada from Qatar, you must first dial 001, then whichever area code is appropriate for that city or region, then the personal number of whoever you wish to call.
