Half my Meta lead phone numbers are disconnected. Are they fake leads?
Rarely fake on purpose. Meta prefills the phone number from the person's profile, and profiles hold old numbers people set up years ago and never updated. The person is real; the contact detail is stale. The fix is to make the phone field require confirmation rather than accept the prefill, and to always capture a second channel — email or a messaging thread — so a bad number does not mean a lost lead.
Prefill is the feature and the problem
Instant forms convert well because the person barely types. Meta populates name, email and phone from the account profile and the submit button is one tap away. That same convenience means the submitted phone number is whatever the profile has held since the account was created, which for a lot of people is a number from two carriers ago.
This is different from fraud. The person genuinely wanted a quote. They simply never noticed which number they handed over, because they never looked at the field.
Making the prefill get checked
- Use a question type that forces confirmation. Some form configurations require the user to re-enter or explicitly confirm a prefilled value. Any friction that puts eyes on the number is worth its cost here.
- Collect two channels. Email plus phone. A stale phone and a live email still reaches a real buyer.
- Ask for the best time to call. It is a soft qualifier, and answering it tends to make people look at the number they just handed you.
- Prefer higher-intent form types. The more deliberate form styles trade some volume for people who actually read what they submitted.
Diagnose before you redesign
Get precise about the failure. A disconnected number, a wrong person answering, and a real person who does not pick up are three different problems with three different fixes, and dispatchers tend to log all three as bad lead.
Ask the team to record the specific disposition, or capture it automatically. Call analysis can classify outbound attempts by what actually happened on the line, which turns a vague complaint into a measurable rate you can act on. If most attempts are no-answer rather than invalid, the problem is speed and cadence, not the form.
Contactability is a source metric
Track connect rate by source: the share of leads from each channel that you reach a live human on. It varies enormously between paid social, search and referral, and it is the number that explains why cost per lead comparisons between channels mislead.
Once connect rate is visible per campaign, form design decisions get easy, because you can see which configurations produce reachable people rather than which produce the most rows. Feeding that back into marketing intelligence alongside booked revenue gives you the full picture: volume, reachability, and what happened after.
