Call Tracking for Offline Advertising
Call tracking for offline advertising gives each leaflet drop, van, sign or event its own fixed UK phone number. Every call to that number is credited to that placement. Call Bullet logs, forwards and records these calls in the same place as your website calls, so offline and online marketing can be compared fairly.

Why is offline advertising hard to measure?
Offline marketing has no clicks. A leaflet, a van or a roadside sign leaves no digital trace, so most businesses judge it by gut feel or by asking callers 'where did you hear about us?' — which people often answer wrongly or not at all.
A dedicated phone number removes the guesswork: if the only place a number appears is the side of your van, calls to it came from the van.
How does offline call tracking work?
Each placement gets its own fixed tracking number. The number forwards to your normal phone, so nothing changes for your team. Call Bullet records the time, caller, duration and outcome of each call against that placement.
This is static call tracking — explained in static vs dynamic call tracking. Your website uses a separate, dynamic pool.
| Placement | Suggested number | Why |
|---|---|---|
| Leaflets in one area | Local area code, e.g. 0113 for Leeds | Feels local, credits that drop |
| Van livery | One number per vehicle or per fleet | Shows whether vans generate work |
| Shop or site signage | Local area code | Separates walk-by enquiries |
| Trade show or event | A number used only at that event | Measures the event's real return |
| Directory listing | One number per directory | Shows which listings are worth paying for |
How do you set up tracking for offline adverts?
Plan numbers before anything goes to print.
- List every offline placement you pay for and decide which deserve their own number.
- Choose fixed numbers on Buy numbers — local codes for local placements, 03 for national ones.
- Name each number after its placement in Call Bullet, for example 'Van — Ford Transit 1'.
- Print or apply the number, and keep it off your website and social profiles.
- Call each number once to check it rings through before the campaign starts.
How do you measure an uplift from offline campaigns?
Some offline marketing works indirectly: people see a van, then search your name and ring the number on your website. To catch that effect, compare total calls in the weeks before and after a campaign, as well as calls to the campaign's own number.
A clear dedicated-number count plus a before-and-after comparison gives a fairer picture than either alone. Be honest in reporting that the uplift is an estimate, while dedicated-number calls are evidence.
How do you keep offline numbers clean?
A number only stays reliable if it appears in one place.
- Never reuse an offline number on the website or Google Business Profile.
- Keep numbers after a campaign ends; old leaflets keep producing calls for months.
- Use a separate number for each distinct area if you drop leaflets in several towns.
- Record each number's placement and start date in its name.
How do offline calls compare with online ones?
Because all calls sit in one Call Bullet log, you can compare cost per call across channels: a £400 leaflet drop against £400 of Google Ads, for instance. Listen to recordings too — offline callers often have different needs from search callers.
Print and radio have their own nuances, covered in call tracking for print and radio.
What are the limits?
A dedicated number only counts people who use it. Customers who remember your name and search for it will reach your main number instead, so offline campaigns are usually under-credited rather than over-credited. For the overall picture, see what is call tracking.
Key takeaways
- Give each offline placement its own fixed number.
- Use local area codes for local placements.
- Keep offline numbers off the website so sources never mix.
- Combine dedicated-number counts with a before-and-after comparison.
- Compare offline and online on cost per call in one log.
Frequently asked questions
How many numbers do I need for offline advertising?
One per placement you want to measure separately — for example one per leaflet area, one per van and one per event.
Do callers notice they are calling a tracking number?
No. It is a normal UK number that forwards to your phone.
Can I keep the number after the campaign ends?
Yes, and you should — printed material keeps producing calls long after the campaign.
Can I record offline calls?
Yes, recording and transcripts can be switched on. Tell callers they may be recorded, as UK GDPR requires.
Should I use a local or 03 number?
Local codes suit local placements; 03 numbers suit national campaigns. Both cost callers the same as a standard landline call.
What if people call my main number instead?
Those calls cannot be credited to the placement. Compare total calls before and after the campaign to estimate the indirect effect.
