Poland and Czechia: Advertising to Ukrainian Diaspora

How large is the Ukrainian diaspora in Central Europe?

Poland hosts somewhere between 1 million and 1.5 million Ukrainians on a long-term basis, with Czechia holding roughly 400,000 to 600,000 — but pin either number down precisely and you're already wrong. Registration data, temporary protection status, and informal residency all count differently, and none of the public counts fully agree. Treat these as directional ranges for planning, not fixed campaign inputs.

UNHCR's regional refugee response data put Poland's registered-for-temporary-protection population near 950,000 to 1 million through 2024, a figure that undercounts pre-2022 labor migrants who arrived on work visas and never needed protection status. Poland's Urząd do Spraw Cudzoziemców (Office for Foreigners) has published PESEL UKR registration counts that run higher once that earlier cohort is added — plausibly 1.5 million to 2 million total, though the desk has not independently verified the upper end and neither should you before committing a media budget to it. Czechia's population is smaller but denser, concentrated in Prague, Brno, and a scatter of industrial towns near the German border.

What this means for media planning

Even at the low end of these ranges, both markets clear the minimum audience size most ad platforms need for stable delivery on language-targeted campaigns. The uncertainty matters for forecasting spend ceilings, not for deciding whether to run the campaign at all.

How do you target it without mis-targeting locals?

You target by language, not by nationality, because none of the major ad platforms let you select an ethnic group as an audience field. Meta's detailed targeting has no Ukrainian checkbox; Google Ads works the same way. What you have instead is language preference, geography down to the city level, and interest signals — Ukrainian media outlets, remittance apps, diaspora community groups — that correlate with the population you actually want.

Layer Ukrainian language selection over a Poland or Czechia geography and most of the precision problem is solved. Meta's system serves language-targeted ads to accounts set to Ukrainian regardless of exact location within the country, which is the mechanism that keeps Polish nationals out of the audience without an explicit exclusion. Add city-level geo for Warsaw, Wrocław, Kraków, and Gdańsk in Poland, or Prague and Brno in Czechia, since diaspora density concentrates there and local advertisers building their own lookalikes rarely bother excluding a foreign-language segment they can't see converting. On Google's Display Network, placement lists built from Ukrainian-language news and community sites do more filtering work than any demographic checkbox could, and cost less to maintain than a custom-intent audience that drifts over time.

One practical trap: retargeting pools built from site visitors don't inherit language targeting automatically. A visitor who lands on a Ukrainian-language page but has their device set to Polish will often get folded back into a general Poland retargeting pool unless you build the segment on page-language behavior, not device settings.

Which language should the creative use?

Ukrainian, not Russian, and not a Polish-first script translated after the fact — even though a large share of this audience is functionally trilingual. Sentiment shifted hard against Russian-language marketing among displaced Ukrainians after 2022, and creative that defaults to Russian because it was the easier translation to source reads as careless at best.

Most media buyers treat the diaspora as a Polish-market extension and reuse Polish landing pages with a translated headline. That's the wrong call, and it costs more than it saves. Staffing-industry surveys published by Polish recruitment firms working directly with Ukrainian workers, including EWL Group and Personnel Service, have repeatedly found that a large share of this population reports only basic or moderate Polish proficiency even after several years of residence — proficiency high enough to work, not high enough to trust a checkout page. Run the arithmetic on a typical setup: a $30 average order value offer, a Ukrainian-language Poland audience in the low hundreds of thousands, and a landing page that's a straight Polish-to-Ukrainian translation. Checkout completion tends to lag CTR on that setup, because the legal footer, the payment prompts, and the customer-service links stay in Polish even after the headline gets translated. Rebuild the funnel Ukrainian-first, end to end, and completion rate closes most of that gap. The lesson isn't translate better — it's that funnel language has to match ad language all the way to the receipt, not just the headline.

What EU and national advertising rules apply?

GDPR governs any personal data collected from this audience exactly the way it governs data from Polish or German users — there is no diaspora carve-out. Platform-level ad transparency rules under the EU's Digital Services Act require Meta and Google to disclose to users why they were shown a given ad, which limits how opaque targeting logic can stay. National consumer-protection bodies add another layer: Poland's UOKiK enforces disclosure and fair-marketing rules on landing pages, and Czechia's equivalent, the Czech Trade Inspection Authority, does the same for advertisers reaching Czech-resident consumers.

None of this is diaspora-specific regulation — it's the general EU compliance stack applied to a specific audience, which is exactly why advertisers underestimate the exposure. One genuine complication: GDPR treats data revealing racial or ethnic origin as a special category requiring explicit consent, and while Ukrainian nationality is not itself listed as special-category data, a data layer that infers it from language, name patterns, or PESEL UKR status sits close enough to that line that a cautious legal read is worth the cost of asking before building it. Financial and insurance offers into this segment trigger the same national consumer-credit disclosure rules that would apply to a domestic Polish or Czech buyer — temporary protection status doesn't exempt anyone from those disclosures, and platforms know it, per Meta's advertising policies on financial products and special ad categories.

What does purchasing power look like in this segment?

Purchasing power here sits below the Polish or Czech median but meaningfully above what the same household could spend from inside Ukraine, and that second comparison is the entire commercial argument for treating this as its own audience rather than a discount version of the domestic one. Median net wages for Ukrainian workers in Poland fall roughly in the range of 70% to 85% of the Polish median, per multiple staffing-industry surveys — a range wide enough that any single figure quoted to you should be treated with caution.

The more useful number isn't wage level, it's payment access. This audience holds Polish or Czech bank accounts, qualifies for BLIK, Poland's dominant instant-payment method used across most Polish e-commerce checkouts per Narodowy Bank Polski payment statistics, and increasingly carries Revolut or similar EU-licensed fintech accounts. That's a structurally different checkout experience from an in-Ukraine buyer working around wartime banking limits or card restrictions. NBP's published data on cross-border remittance flows to Ukraine also implies disposable income beyond bare subsistence — money moving from Poland to family in Ukraine means income was left over in Poland first.

Which offers convert with this audience?

Offers that solve a real friction of relocation convert best: legal and residency-document services, Polish or Czech language courses, telecom plans, remittance and fintech products, and job placement. What underperforms is recycled domestic-Poland creative with a translated headline slapped over an unrelated offer — this audience is specific enough that generic e-commerce and dropshipping funnels convert below their Polish-market benchmarks.

• Residency and documentation support — PESEL UKR registration help, translation services, permit-renewal reminders.
• Language learning — Polish or Czech course platforms and tutoring subscriptions.
• Telecom — prepaid SIM plans priced for a resident who still calls family in Ukraine.
• Remittance and fintech — transfer apps, multi-currency accounts, comparison tools.
• Employment — job boards and staffing-agency lead generation, already a sizable category given that firms like EWL Group and Personnel Service actively recruit this population.

None of these categories tolerate loose claims. Financial products need the same consumer-credit disclosures as any EU offer, and anything adjacent to immigration outcomes needs to describe a service, not promise a result the advertiser doesn't control — promising visa or residency outcomes risks both a platform ban and enforcement from UOKiK or the Czech Trade Inspection Authority. Build the segment as its own line item, with its own creative, its own landing-page language, and its own compliance pass, rather than as a targeting tweak bolted onto an existing Polish campaign. At the population sizes involved, that overhead pays for itself.

Frequently asked questions

Is it legal to target ads specifically at Ukrainians living in Poland?

Yes, but only through language and location targeting, not nationality or ethnicity, which platforms don't offer as a field. GDPR still applies to any data collected, and inferring ethnic origin from proxies like name patterns sits close to GDPR's special-category rules, so a cautious legal read before building that data layer is worth the cost.

Should diaspora creative be in Ukrainian or Russian?

Ukrainian, not Russian. Sentiment against Russian-language marketing hardened sharply among displaced Ukrainians after 2022, and platforms and staffing surveys both point the same direction — proficiency in Polish or Czech is often functional, not deep enough to trust a checkout page in that language either.

How is the Ukrainian diaspora audience in Poland different from advertising directly into Ukraine?

Payment access is the core difference. Diaspora users in Poland and Czechia hold EU bank accounts and use BLIK or Revolut, while in-Ukraine buyers work around wartime banking limits and rely more on cash-on-delivery or informal transfer, which changes checkout design and expected conversion rate.

What's the fastest way to build a Ukrainian-language audience on Meta?

Layer a Ukrainian language setting over a Poland or Czechia country target, then narrow to cities with known diaspora density like Warsaw, Wrocław, Prague, and Brno. This filters out most Polish or Czech nationals without needing a separate exclusion audience, per how Meta's language-targeting mechanism actually serves ads.

Do offers to this audience need Polish VAT registration?

Standard EU VAT rules apply the same way they would for any Poland- or Czechia-directed offer, based on where the buyer and seller are established, not on the buyer's nationality. Temporary protection status doesn't change VAT or consumer-credit disclosure obligations, so treat this segment's compliance requirements as identical to domestic ones.
