ACTIVE COMPANIES BY REGISTERED-OFFICE POST TOWN (WHERE THE PAPERWORK SITS, NOT NECESSARILY THE WORK) · COMPANIES HOUSE PUBLIC RECORD, AUGUST 2026
The five busiest post towns hold 45 per cent of them and London alone 39 per cent. Selling nationally, those towns are most of the market. Selling locally outside them, expect a small pool, so cover a county or a region rather than one town.
A worked example: 62012, registered office in London, incorporated in the last ninety days, from a pool of 110,075. Each lead you get arrives with a working website and a real email, and the director's name when the record has one. If we cannot complete one, you pay nothing.

How to read SIC 62012
SIC 62012 reads as division 62 (computer programming, consultancy and related activities), group 620, class 6201, then the full five digits, inside section J, information and communication. A company picks its own codes, up to four, and Companies House does not check them, so 62012 is the company's own description of what it does, and 89,176 list it first where 110,075 list it anywhere.
Who sells into division 62
Contractor-heavy sectors reward specialists, and this division has plenty. Accountants built around IR35 and personal service company compliance work it daily.
About SIC 62012
Can I get a director's name and email for SIC 62012 companies?
The director's name comes from the Companies House record when it names one. Each lead arrives with a working website and a real email, and if we cannot complete one you pay nothing.
Are most SIC 62012 companies remote-first?
Many are. A registered office is often a founder's own address rather than a workplace, so do not read territory from the registered postcode alone here. Check the contact page on the company website as well.
