TL;DR: If you want a ZoomInfo alternative because you sell into Europe, keep ZoomInfo for your US pipeline. For Europe, stack several European providers in a waterfall to find more mobiles. Then check every number before your team dials, because a full list still holds wrong, dead and personal numbers.
You run out.
That is the moment most teams start looking for a ZoomInfo alternative. They start with ZoomInfo, call their best European prospects, and the good numbers dry up. The mobiles that are left ring a switchboard, reach a stranger, or reach someone's home phone.
We used ZoomInfo in our own European campaigns. Our verdict: good database, limited for Europe. After calling 200 good prospects, you run out.
So the team goes shopping for a new tool. That is the wrong first move. Here is what we do instead.
Is ZoomInfo good for European phone numbers?
ZoomInfo has a good database, and its depth sits in North America. For European mobiles it thins out fast. Our callers found enough numbers for the first 200 strong prospects on a European list. After that, the right numbers ran short.
One UK buyer on Trustpilot measured it over a full year. Across a 12-month contract, "over 50% of the information was inaccurate," phone numbers included.
Its global coverage page promises "one database for every region you sell into" and counts company locations, with no figure for European mobiles (as of October 2026). Its data FAQ says it provides "accurate direct dial and mobile phone numbers" and gives each profile a confidence score.
European mobiles are hard for every provider. Senior buyers keep their mobile private, so it rarely shows up on a website or a signature. And cross-border workers carry foreign phones, which brings its own trouble, as you will see below.
Should you replace ZoomInfo with a ZoomInfo alternative?
No. Keep ZoomInfo if it works for your US pipeline. Swapping one big database for another big database moves the same European gap to a new invoice. The fix for Europe is to add European providers on top, run them in order, and check what comes out.
ZoomInfo prices on a quote. Its pricing page says the price depends on features, the number of licences and credit usage (as of October 2026). You already negotiated that contract. Do not throw it away because one region is thin.
If your team only calls the US, TitanX and SureConnect are the picks for checking numbers. For Europe, that is the job we built Answrd for.
How do you build a European phone stack next to ZoomInfo?
Stack several providers and run them as a waterfall. A waterfall asks provider one for a mobile. If it finds nothing, provider two gets the contact, then provider three, and so on. You pay each provider only for the contacts the one before it missed.
You can buy a waterfall from a tool like FullEnrich, or build your own in Claude Code with each provider's API. We run ours on every European list.
Here is what a waterfall did for us. A waterfall of eight providers on 461 senior IT and security contacts in the Netherlands, Belgium and Luxembourg found a usable mobile for 85% of them (392 of 461). Twenty of the misses only had a mobile from a neighbouring country. That means a personal phone, so we took them out.
Order matters. A tier of five low-cost providers found usable numbers for 3 of 71 senior security contacts in Germany, Austria and Switzerland, about 4%. Most of what they returned were US numbers for US-based people. On another list, one waterfall provider found 14 of 15 senior Dutch and Belgian security mobiles after a seven-provider cheap tier had found 3 of 19.
What should you add to the stack?
These are providers we would look at for European mobiles. Each line is what the vendor says on its own homepage, as of October 2026. No ranking. Test them on your own contacts.
- Kaspr: pitches itself on European contact data, with a Chrome extension that shows phone numbers and emails on a prospect's profile.
- Eficia: calls itself a phone number enrichment platform.
- FullEnrich: a ready-made waterfall. It says it pulls from 20+ data vendors and that you only pay for mobile numbers.
- Tomba: an email and phone API. Its site says the phone finder covers contacts outside the EU, so check that before you add it for Europe.
- Forager: says it holds more than 200 million mobile phone numbers.
- Wiza: says it finds work emails, direct dials and cell numbers.
- Lusha: says each phone number shows the date it was last updated.
Watch out for shared wholesaler numbers
Several providers buy from the same wholesalers. They can hold the same numbers. So provider five can return the number provider two already gave you, under a new logo and a new bill.
Track what each provider adds that the others did not. When a provider stops adding new numbers on your countries, cut it. Our post on running a phone waterfall goes deeper on order and cost.
Why does a full list still miss the right person?
Coverage counts the contacts that have a number. A full list still holds wrong numbers, dead lines, landlines and private phones. Your reps find them one dial at a time.
Here is what we measured. We took 2,626 mobiles from one provider in our CRM:
- 75.6% passed our basic checks: right country, a mobile, and not a known bad number.
- 38.9% of the numbers our teams dialled were answered.
- 17.8% reached the person we wanted.
Most of the failures were wrong-country numbers and landlines. The weakest countries were Belgium (40% passed), Ireland (45%) and Switzerland (51%).
Buyers who track their own lists see the same pattern. A US buyer on Trustpilot who prospected with ZoomInfo for 6 months found 30 to 40% of contacts were years old, with numbers out of service or at other companies. A buyer on Reddit found "half the mobile numbers are dead or wrong." Every provider has gaps like these. Keep the one you use, and check its numbers.
Billing hides this too. On one Benelux list, a single provider charged us for 27 hits. One was a usable own-country mobile. That works out to about $20 per usable number. Most hits were foreign mobiles and direct lines.
Then there are the calls. We have reached a spa instead of an executive. We have reached the wife of a head of department. We have called people who retired 10 or 15 years ago.
Why personal mobiles are the biggest risk in Europe
In our own campaigns, providers have returned numbers from a different country than the person. A Luxembourg contact on a Belgian or French mobile is a cross-border worker's private phone. We take those out. Personal numbers are the biggest problem in Europe right now.
The people who answer them get angry, often about GDPR, most of all in France and Switzerland. They have a point. The UK regulator's guide to the accuracy principle says personal data must be "accurate and, where necessary, kept up to date." The same principle sits in Article 5 of the EU GDPR. A wrong number on a name is inaccurate personal data about two people.
How do you check numbers before your team dials?
Check every mobile after the waterfall and before the dialler. Keep ZoomInfo, keep your European providers, and add one step at the end. Your reps then call only numbers that pick up, and the wrong, dead and personal numbers never reach them.
Here is the routine we run:
- Pull from ZoomInfo and your waterfall as usual. Keep the stack you trust.
- Strip the obvious misses. Wrong country, landlines, numbers you already know are bad.
- Check every mobile that is left. Flag wrong and dead numbers before the first dial.
- Dial only what passes.
- Check again before you retarget. A list you checked in March has aged by September.
That last check is what Answrd does. You upload the numbers you already have. You get back the numbers that pick up, with the wrong and dead ones flagged. You pay €0.75 per verified number, with credits that never expire. We do not sell data. The promise is 3x your pickup rate.
The results on our own campaigns:
- Engineering services campaign: real pickup went from 6% to 17% after verified numbers.
- Security software campaign: 12.8% real pickup, against a history of 2% to 5%.
- One recent list: of 131 numbers checked, 13 were bad. Of the good ones, most reached the right person and the rest a named voicemail.
Compare that with one bad day we logged: more than 200 dials to get about 3 people on the phone. To see what your list costs per conversation, run it through the pickup rate calculator. A line that is live can still belong to the wrong person. Our post on the limits of HLR lookups explains why.
Frequently Asked Questions
Is ZoomInfo accurate?
In our European campaigns it was a good database that ran thin after the first 200 strong prospects. Judge it on your own list: count how many numbers reach the right person.
Is ZoomInfo free?
Partly. ZoomInfo's FAQ says a free version is available through the ZoomInfo Lite package (as of October 2026). The full platform is paid and priced on a quote.
What is the best ZoomInfo alternative for Europe?
No single database covers European mobiles well on its own. Keep ZoomInfo if it works for your US pipeline, and add European providers in a waterfall. Then check every number before you dial, because a filled list still holds wrong and personal numbers.
Does ZoomInfo have mobile numbers for Europe?
Yes, some. Its coverage page gives no figure for European mobiles (as of October 2026). In our campaigns, the good ones ran out after about 200 strong prospects.
How much does ZoomInfo cost?
ZoomInfo does not publish prices. You get a quote based on features, licences and credit usage. Some packages offer a free trial.
Can you use ZoomInfo and other providers together?
Yes, and for Europe you should. Run ZoomInfo first, since you already pay for it, then the European providers. Track what each one adds. Several providers share wholesalers, so the fifth one adds less than you expect.
Why do my European numbers reach the wrong person?
Most often the number is a private mobile, sometimes from another country. Other times it is a landline, a dead line, or a number that moved to someone else. Every provider has this problem, so check numbers before you dial.
Keep ZoomInfo. Check every European number.
Keep ZoomInfo for your US data. The best ZoomInfo alternative for Europe is a stack: European sources in a waterfall, then a check on every mobile before your team dials. That is how a European list keeps producing conversations after the first 200 prospects.
Start with your own list. Test 100 numbers free, no card needed, and see how many of your current mobiles reach the right person. If you would rather talk it through, book a 15-minute call.
