The number you choose shapes how customers perceive you before anyone says hello. A city code says “we’re local”. A freephone number says “call us, it’s on us”. A national number says “we cover the whole country”. Here is how the four main types compare and when to use each.
Local (geographic) numbers
A local number carries a city or regional area code, such as 020 for London, 030 for Berlin or 212 for New York.
Best for: sales teams entering a market, branch offices, businesses that want to look established locally.
Cost to caller: a normal local or national call rate. For you, a monthly fee and usually free or low-cost inbound minutes.
Watch out for: some regulators, Germany for example, expect a geographic number to be used by someone with a presence in that area, so address verification is common.
National (non-geographic) numbers
National numbers work across a whole country without pointing to a city. The UK’s 03 range is a good example: calls cost the same as a call to an 01 or 02 number and are included in most mobile bundles.
Best for: national brands, public-facing services, companies that don’t want to favour one city.
Toll-free numbers
Toll-free numbers, such as 0800 in the UK and Germany, 1-800/888/877 in North America or 1800 in Australia, are free for most callers. You pay for the inbound minutes instead.
Best for: customer support, order lines, direct-response advertising.
Watch out for: calls from abroad usually can’t reach a domestic toll-free number, and in some countries mobile callers may still pay. See toll-free vs local numbers for support.
Mobile numbers
In some countries regulators allow mobile-range numbers to be allocated to virtual services, sometimes with SMS. Rules are stricter than for landline ranges and availability varies a lot by country.
Best for: services where customers expect a mobile number, or where SMS on the same number matters.

Many businesses use more than one
A common setup is a local number in each target city for sales, plus one toll-free number for support. Because all of them can route to the same phone system, customers get the number that suits them and your team answers in one place.
Frequently asked questions
Can I switch a number from local to toll-free later?
Not the same number. Each number belongs to a specific range. You can add a toll-free number alongside your local one and route both to the same place.
Which type is cheapest to run?
Local and national numbers usually have the lowest running cost, because inbound minutes are rarely charged. Toll-free costs more as call volume grows.
