What we supply

What arrives, column by column.

Every column of a CallWave list, explained: what it is, where it can come from, and what a blank one means. Telemarketing team or telesales floor, the file is the same, and a blank on it means unknown. Never none, and never small.

Basic info

The record itself.

Name, address and number: the three columns every call starts from.

Company name

The business as it trades publicly, because that is the name your caller needs to say. Where the register names a company behind it, the registered name, company number and incorporation date ride along. Where no company can be matched, you get the trading name alone. A guessed registered name is worse than an honest gap, so we never guess one.

The rule · A registered name is matched, never guessed.

Company address

The trading address as published, not a registered office two counties away. It lets a file be cut by area and tells a caller which branch answered before they say the wrong town out loud.

The rule · A blank means unknown, never that the business has no address.

Phone number

The number the business itself publishes, with its type marked, because a mobile answers differently to a front desk. Premium-rate and non-geographic numbers are dropped at collection. Nothing is dial-tested, and no accuracy percentage is published, because none could be evidenced.

The rule · Premium rate never ships. Nothing is dial-tested, and the file says so.
Decision maker

A name to open with.

“Can I speak to Michael?” opens a different call to “can I speak to the owner?”.

The likely decision maker

Where the public register names a director, you get that name. Where it names nobody, a suggested name for who runs the business, worked out from its own website and public listings, and the supply guide says which kind you are holding. Where nothing can be established the cell is left blank, because an invented name costs a caller credibility in the first breath.

The rule · A name is never invented. The supply guide says which kind you are holding.
Business numbers

The shape of the call, before you dial.

Three sortable facts that decide which rows are worth a senior caller’s morning.

Business age

Years trading, from the incorporation date on the public register, so it is a fact rather than an estimate. Brand new businesses are marked visibly: for some campaigns they are the whole point, for others the rows to skip.

The rule · Age is a register fact, not an estimate.

Business size

A size band read from what the business files publicly. Size decides who answers the phone and what an order is worth.

The rule · Bands, never figures nobody could evidence.

Business turnover

A turnover band on the same rule: the fastest qualifier there is for sorting a long file. Where the filings support no band, the cell is blank.

The rule · A blank means unknown. Never none, and never small.
Screening

Checked before it reaches you.

Two registers protect UK phone lines, and cheap files check one or neither. Every CallWave order is checked against both, in one pass, with one date.

TPS · the personal register

Covers lines belonging to people rather than companies, which in business calling means sole traders and many partnerships. A number found on it never reaches your file, and it stays marked in our records, so the same number is screened out of future work as well.

The rule · A listed number never reaches your file.

CTPS · the corporate register

Covers company lines: the half of screening many suppliers skip, and the recent heavy fines involved callers ringing both registers unchecked. Checked on every order, in the same pass, with the date printed on the file.

The rule · One check, both registers, one date.
Signals

What the ground is like.

Two marks that describe the area around each business, never the business itself, so a long file gets worked in a sensible order.

Area development

Where new building and growth is happening, drawn from public data. Growth areas first for a campaign selling into change, last for one that wants the settled.

The rule · Marks describe the ground, never the business.

Area wealth

Spending power around the business, built from public price data. Two identical businesses in different towns are not the same call.

The rule · One meaning everywhere the mark appears, screen and sheet alike.
Verification

Coming, and not before it is real.

Plenty of suppliers imply their numbers are tested. Ours are not.

Number connectionCOMING

No number on any file has been rung, and we publish no accuracy percentage because none could be evidenced. Connection checking is on the roadmap: when it arrives it will work the way screening already does, a check with a date printed on the face of the file. Until then, what you rely on is already dated: collection after your order, and the screening check.

The rule · No claim before the mechanism exists.
What arrives

Two files, ready to work.

The spreadsheet

Every column above, one row per business, sortable. Blanks are honest: unknown, never none.

The supply guide

One page in front of the data, written to be read by the caller and forwarded to whoever asks: the source in plain English, your written reason for calling, the permitted use, and the removal route.

Questions

About the file.

What does a blank cell mean?

Unknown. It never means none and it never means small, and the supply guide says so in those words.

Where does the decision maker name come from?

The public register, where it names a director. Otherwise a suggested name from the business’s own website and public listings, marked as such. Never a guess.

Are email addresses included?

No. We collect none, hold none and supply none. The data is for live telephone calls.

How fresh is the file?

Collected after your order, for your order alone. After thirty days our copy is deleted, so a repeat is collected fresh.

Are the numbers dial-tested?

No. No accuracy percentage is published either, because none could be evidenced. What is evidenced is the collection and the screening, both dated on the file.

Can a file be sorted by size or age?

Yes. Age in years from the register, size and turnover as bands, all sortable columns.
