This is the fourth Fed Cup meeting between Belarus and Estonia, who both competed under the USSR flag prior to 1992.
Belarus leads the series 2-1, but it was Estonia that won the most recent tie between the two nations. The teams have never played a best-of-five tie, having only previously met in the Europe/Africa Zone Group I event.
At stake for the Belarusians is a chance to equal their best performance in the competition by reaching World Group II. Estonia, meanwhile, is looking to keep its place in World Group II for the second year running.
