Wales currently has 2,800 Ukrainians residing there with host families who agreed to provide housing for at least six months.
When that time period finishes in the fall, there may be a need for additional support.
Ministers expressed gratitude to the hosts but emphasized the need for more households to participate.
Jane Hutt, the minister of social justice, said: "We hope hosts and Ukrainians will agree to renew many of those arrangements, but we need more hosts to support people who can't stay where they are."
A survey by the Office for National Statistics, which indicated that almost a quarter of hosts anticipated having to evict their visitors after six months, was mentioned by officials.
The request for additional hosts comes as expenses are rising, but Ms. Hutt remarked that Wales has already demonstrated its generosity and promised that "we would stand up to the plate once again."
2,800 more combat refugees are staying in temporary housing. Hotels and residence halls at universities have been included in this. Numerous more have visas but haven't entered the country.
A few people are being offered spots at two unnamed vacation parks.
The Welsh government established a super-sponsor program earlier this year with the intention of housing 1,000 refugees; however, the program's acceptance of new applicants was suspended in June and is now on hold.
Also asked to register are homeowners who have rooms available for up to 30 days for those in need of short-term emergency housing.
