JERUSALEM — Weeks ahead of the expected completion of a UN database of companies that operate in Israel’s West Bank settlements, Israel and the Trump administration are working feverishly to prevent its publication.

While Israel is usually quick to brush off UN criticism, officials say they are taking the so-called ‘‘blacklist’’ seriously, fearing its publication could have devastating consequences by driving companies away, deterring others from coming, and prompting investors to dump shares of Israeli firms.

Dozens of major Israeli companies, as well as multinational firms that do business in Israel, are expected to appear on the list.

‘‘We will do everything we can to ensure that this list does not see the light of day,’’ said Danny Danon, Israel’s UN ambassador.

The UN’s top human rights body, the Human Rights Council, ordered the compilation of the database in March 2016, calling on UN rights chief Zeid Ra’ad al-Hussein to ‘‘investigate the implications of the Israeli settlements on Palestinians.’’

The international community overwhelmingly considers the settlements, built on occupied land claimed by the Palestinians for a future state, to be illegal. Israel rejects such claims, citing the land’s strategic and religious significance, and says the matter should be resolved in negotiations.

Israeli officials say that about 100 local companies that operate in the West Bank and East Jerusalem have received warning letters that they will be on the list. In addition, some 50 international companies, mostly American and European, also have been warned.

The companies have not been publicly identified, but one official said they include Israeli banks, supermarkets, restaurant chains, bus lines, and security firms, as well as international companies that provide equipment or services used to build or maintain settlements.
