Sending a fax to the UK from faxio.app works the same way as a fax within the US: upload the document, choose the country, type the number, pay $2.99. The part people get wrong is the number. UK fax numbers are usually written with a leading 0, and that 0 has to go once +44 is in front of it.

  • Country code: +44
  • What to type: +44, then the number without its leading 0
  • Price: $2.99 per fax of up to 10 pages, the same as a fax within the US

The country code and number format

UK numbers are written with a leading 0 for dialling inside the UK: 020 for London, 0161 for Manchester, 0121 for Birmingham, 028 for Northern Ireland. From abroad that 0 is left off and +44 takes its place.

Written in the UK Type after choosing United Kingdom (+44) Dials as
London: 020 3808 9463 20 3808 9463 +44 20 3808 9463
Manchester: 0161 xxx xxxx 161 xxx xxxx +44 161 xxx xxxx

UK numbers are often printed as +44 (0)20 .... The (0) is there for people dialling inside the UK; leave it out.

If a number is written with a 00 in front, such as 0044 ..., the 00 is the international prefix used in Europe. Leave out the 00 and the 44; the Country list already supplies +44.

Spaces, dashes and brackets in the number do not matter; Faxio uses only the digits. Do not type 44 again in the number box, because the Country list already adds +44.

Numbers that will not work

Faxio does not send to mobile or premium-rate numbers in any country. UK mobile numbers start with 07, and numbers starting with 09 are premium-rate. Freephone numbers starting 0800 or 0808 may not be reachable from outside the UK; if you only have one of those, ask the recipient for a geographic fax number.

Also make sure the number is a fax line. Many organisations list a phone number and a fax number side by side, and a voice line will ring without a fax machine ever answering.

How to send the fax, step by step

  1. Get the document ready. A PDF is simplest; JPG, PNG and phone photos are accepted too. One fax holds up to 10 pages.
  2. Open faxio.app/send and drop the file in, or click to upload. You can add up to 10 documents.
  3. Choose United Kingdom (+44) in the Country list. It is listed under Most used, near the top.
  4. Type the fax number without the leading 0, for example 20 3808 9463.
  5. Add a subject if you want a cover page, and an email address if you want the delivery confirmation sent to you. The confirmation is useful as proof of transmission.
  6. Press Send fax (or Buy credits & send if you have no credits yet) and pay by card. The fax appears under Your faxes, and its status moves from Sending to Delivered, usually within a few minutes.

We have confirmed delivery to the UK in our own test sends. The Faxio Android app sends to the same countries at the same price.

What it costs

Faxio charges the same for every destination, so a fax to the UK costs the same as one within the US:

Option Price Per fax
1 fax (up to 10 pages) $2.99 $2.99
5 faxes $9.99 $2.00
15 faxes $24.99 $1.67

There is no subscription, and credits never expire. If you fax abroad every week, the Unlimited plan is $14.99/month; up to 5 faxes a day on it can go abroad, within its fair use of 15 faxes a day and 100 a month. The details are on the pricing page.

If the fax does not go through

Busy lines are retried automatically. If the fax still cannot be delivered, it is marked Failed and the credit goes back to your balance automatically, so a failed fax costs nothing. Fix the cause and send it again.

The usual causes on a fax to the UK:

  • The leading 0 is still in the number. Remove it and resend.
  • It is a voice line or a mobile number. Check with the recipient that it is a fax line on a landline.
  • The machine is switched off or out of paper. Office fax machines are often unattended outside business hours, so check the local time in the UK before you send.
  • A communication error on a long route. International lines are more prone to these than domestic ones, and a retry often works. Splitting a long document into shorter faxes can also help.

For what each error means, see why a fax is not going through. For file formats and delivery statuses in general, see how to send a fax online.
