Range: 070 - includes all UK personal number tariffs, tariffed from D rate up to PN2.
dmClub K-rate numbers have the prefix 07040-9

Cost to call: BT landline rates are 37.5p, 25p and 12.5p per minute Day, Night and Week (inc. VAT), more from mobile operators who don't like Personal Numbers!

Image: Personal Numbers are intended for personal/private use.

Cost of ownership: In general these numbers are totally free to the owner when used to forward to UK landlines and many International landlines. There may be cost-saving ServicePlans that trade a fixed monthly fee for discounted international divert rates.

International accessibility: Medium.
Note that calls from overseas have reduced international reach

Regulatory issues: This range has always been a little controversial and is likely to be renumbered in the next 2-5 years. Any numbers registered with 070 providers will be transferred when this happens.
dmClub will support all users in this changeover period, including the early release of numbers that work on both ranges.

Mobile accessibility: All UK operators overcharge for calls to Personal Numbers, perhaps they've viewed them as a threat in the past.

Typical Applications: Often used as "on call" numbers where it's convenient to change the destination (which is usually a mobile) on the fly. Also good for privacy and anonymity. Some companies use these relatively expensive to call numbers to dissuade low-value users from wasting their time unless it's important!

Choose a gold number to match your personalised number-plate.

Alternative low ownership cost options that aren't quite so expensive to call include 070-D, 0870 and 0871

Those that might want to divert to more expensive international destinations without charge should consider 070-PN2 numbers - but they are even more expensive to call.
