   Useful information to know for UK portability

When you wish to port UK numbers, there are different factors that you must consider

• Number detail: Are the numbers Geographic (belongs to a specific area in the UK, a local address is mandatory) or Non-Geographic (does not belong to a specific area in the UK, a national address is mandatory). Are these numbers part of a Single-line [Single-lines, are lines that terminate on a single socket, and do not have any other form of associated numbers] or Multi-Line [Multi-lines, are lines that terminate on equipment such as a PBX]?

• Who is the current communications provider: This does not specifically mean the service provider who bills you every month. Indeed, they could be a reseller, if it’s the case, the customer needs to contact their current carrier/reseller and ask for the current underlying carrier. In order words, which carrier does the reseller use to host their numbers in the United Kingdom.

• Who is the Range Holder: This is the carrier who owns the number block originally, ie. the assigned block from OFCOM.

Time scale for Local / National / Toll-free UK numbers

(Approximately, although it varies from case to case and how difficult the Losing Communications Provider wants to be).

N.B These time frames are expected SLAs between carriers. In the event of no response from the Losing Communications Provider or the Range Holder within the time frame above, an escalation will be made to the relevant party.

Time and date of port

It is possible to select the date you wish to port on (we must be given the specific date prior to entering the request and it has to be within the time frame mentioned in the table above). The standard time for most Local and National ports to be triggered is 10 AM GMT. All Toll-Free ports (unless specified otherwise) take place between 00:00 and 04:00 AM GMT on FOC.

However, this does not mean that your number will port at that specific time on FOC (like in the case of US ports).

In the UK, ports can take up to 2 hours to complete once triggered, and a little bit longer for the portal to reflect this due to our post-port check.

We have experienced in the past that on FOC, the Losing Communications Provider does not trigger the port at 10 AM. If this happens, we chase them every two hours, but there is a chance that your port does not get activated until 6 PM on FOC.

Once we have received FOC, it is possible to change the port date if an issue arises.

• We require at least 48 hours prior to FOC to be able to move the date if the Losing Communications Provider is the Range Holder.

• We require at least 72 hours prior to FOC to be able to move the date if the Losing Communications Provider isn’t the Range Holder as there are more parties to contact in order to make the change.
