Phone Number Formats to Call Denver from India

In the US, phone number formats are highly standardized with no variation across the country. As well, landline and mobile phone numbers are formatted exactly the same. It is not possible to tell, simply by looking at a American phone number, whether it is a mobile or landline number - and it doesn't matter for dialing purposes.

All United States phone numbers are 10-digits long and include a 3-digit area code and 7-digit local subscriber number. Increasingly, the same region may have multiple area codes. Local subscriber numbers are unique within an area code. Please check here for more information on Denver area codes.

United States phone numbers may be written to include a leading ' 1 '. This ' 1 ' can serve as either the United States country code for inbound international calls or as a national direct code for national long distance dialing in the US.

If the Denver phone number you have does not contain the full 10-digit phone number, then you'll need to double check to find the correct number.
