Yes - note there is an equivalent problem in the Internet in terms of the IP
address range.
There is a new standard which incorporates more "digits" - but it is
difficult to deploy due to impact on network planning, configuration,
equipment compatibilities etc etc.

The domain name is an identifier that can refer to a physical IP address.
You can have multiple identifiers refer to the same physical IP address.

Likewise a 1800 number (especially one that is linked to alphabetic
characters on a telephone keypad) can operate a bit like a domain name.  You
could theoretically add different number ranges like 1900, etc for the
equivalent of "", "" etc.
Note the telephone number has a direct relationship to charging/billing
which the domain name does not.
