Phone numbers for billboards, TV and radio

One number, three very different moments

A billboard, a television spot, and a radio ad all ask the same thing of a phone number, and each one asks it in a different way. On a billboard the number is read by a driver in motion. On television it is shown on screen and spoken at once. On radio it is only heard, with nothing to look at and no way to rewind.

That difference is why a billboard phone number and a radio number are not always the same problem. A number that looks good in large letters can sound awkward when spoken, and a number that sounds smooth can be hard to read from a distance. The goal is a number that survives all three moments, and that goal shapes every choice that follows.

A word number helps in all three, and that holds for a phone number for TV and radio ads as much as for a sign. A word is a single thing to recall, where a string of digits is seven separate things. It can be read as one unit on a billboard, shown as one unit on screen, and said as one unit on the air. That is the main reason firms that advertise across media often choose a number built from a word.

Advertisers also like a single number across channels because it makes the results easier to read later. When every spot, sign, and spoken line points to the same number, the firm has one thing to promote and one thing to teach. A toll-free number is the usual choice when the audience spans several markets.

How to say a phone number in an ad

Knowing how to say a phone number in an ad is a small craft, and most of it is common sense. The speaker should slow down at the number, because the number is the point of the whole spot. Everything before it only earns the listener's attention, and the number is what that attention is for.

Say the word first, then the digits, then the word again. A listener who catches only part of it still has two chances to get the rest. Pausing briefly before the number signals that something important is coming, and pausing after it gives the listener time to write or to commit it to memory.

Keep the surrounding copy short. A crowded line buries the number, and a clean one lets it stand out. Do not say the number once and then move to a closing line. Repeat it at least once near the end, because a listener who was distracted the first time has a second chance.

Match the spoken form to the written one. If the screen shows the word and the digits, the voice should say the word, and the digits should match the keypad exactly. A mismatch between the two forms confuses callers and creates wrong numbers, so check the digits by hand.

Then test it. Read the script aloud to people outside your business, and ask them a day later what number they remember. If most of them can tell you, the spoken version is working. If most cannot, change the number or the delivery before the spot airs.

Reading a billboard number at a glance

Reading time is the hard limit on a billboard. The driver passes it quickly, from a distance, usually while watching the road. Every extra word, every second line, and every decorative flourish takes a share of the little time available, and the number is the thing that gets squeezed.

Our research notes put it plainly. Personal injury campaigns often have only a few seconds to make a number stick.

Some people quote a rule of thumb for how many words a billboard can hold. We do not repeat it as a figure, because it is a rule of thumb and not a measured result. What the reasoning gives us is simpler: the fewer things a sign asks a driver to read, the more likely the driver reads the one that matters.

So a billboard number should be the largest thing on the sign after the headline, set in plain type with high contrast, and written the way people will say it. A word number lets the sign carry one short word where a plain number carries seven digits, and the word is easier to take in at a glance.

Leave out anything that does not help the driver call. A slogan, a second number, and a web address all compete with the number. If the sign has to carry more than one thing, decide which one matters most, and make the number that one.

Recall on radio and visual media

Radio is the clearest test of a spoken number, because the listener has only the sound. Vendors that sell word numbers publish recall figures for radio and for visual media. They are claims by sellers, not independent studies, so they appear below with their labels and links, and none of them is a promise about your results.

Read these the way you would read any claim from a seller. They compare word numbers with plain digits, and they measure recall, which is whether people remember a number. Recall is not the same as a call, and the sources do not say how the audiences were chosen. For a closer look at how to weigh figures like these, see do vanity numbers increase calls.

Television sits between the two. A number on screen can be read, and the same number can be heard, so it gets two chances at once. That helps, but it also means the two forms have to agree. If the screen shows one pattern and the voice says another, the viewer has to choose, and some will choose wrong.

Choosing the number for every channel

Start with the market. A firm that advertises in one city can use a local number with a familiar area code, and a firm that reaches several markets often prefers a toll-free number. Each type is covered on its own page, and the toll-free numbers page and the local numbers page explain how each works.

Then look at the practice. Injury firms often advertise on billboards and television, where the number has to be read and heard quickly. The page for injury lawyers shows word patterns built for that work, with the digits beside each one.

A toll-free option has a practical advantage here, since an 800 number creates one memorable intake path across billboards, TV, radio, digital, and referral campaigns.

Whichever number you choose, it can forward to the intake system you already use, so the choice does not force a change inside the office. Every guide is listed in the articles index.

Advertising rules and next steps

Rules on lawyer advertising differ by state. Check yours before you print a number. Legal800 is not a law firm and gives no legal advice.

Before a number goes on a sign or into a script, read your state's advertising rules, and keep the number free of words that suggest a result. Then test the spoken and written forms with people outside the firm. When you are ready, ask for options and name the words and patterns you prefer.
