Range: 0845 (dmClub numbers begin 0845 686)

Cost to call: BT landline rates are 4p, 2p and 1p per minute Day, Night and Weekend (inc. VAT), more from mobile networks.

Image: Indicates a fairly big (possibly national) company. Similar to 0800 but with less of a sales/customer acquisition focus.

Fixed Cost of ownership: The owner may pay setup and rental but not call fees (unless the call needs to be diverted to an expensive destination such as mobile or high-tariff international regions). This makes them the cheapest to call option that has fixed costs of ownership. There may be a payout when diverting to the cheaper locations
dmClub 0845 numbers will divert to landlines in the Big34 countries without charge. Many popular destinations will even result in a modest payout - up to 0.75ppm for UK landline or 1.05ppm for VOIP-trunk

International accessibility: Good.

Regulatory issues: Ofcom have been wondering what to do about this range, but our best guess is that it will be unlikely to change in the next 2 years or so.

Mobile accessibility: All UK mobile operators overcharge for calls to 0845 numbers

Typical Applications: Usually in a soft sales or support situation where callers are not so cost-sensitive and the owner wishes to have fixed costs.
Often compared to 0844 numbers, although the public are more familiar with 0845 (which are also cheaper to call, specially at weekends)

Choose a gold number to add to the professional feel for a fairly modest additional one-off cost. As 0845 is generally less salesy than (say) 0800, the gold number premium is usually smaller.

0845 numbers are often suitable for IVR services (eg. dmSwitchboard)

0800 numbers may be more appropriate if you're fighting for business as they're cheaper and more familiar.

0844 numbers flat rate 5ppm with slightly lower ownership costs (and slightly bigger payout). There are no changes coming on the tariffing.

UK Local or 020-7 numbers are cheaper to call from mobiles and have superior international accessibility, but there's no payout
