The Banco Central de la República Dominicana has a policy of refusing to exchange banknotes with “excessive” writings on them. In those cases it may impound them. Commercial banks may refuse to accept them.

As a practical rule, if a banknote has a written initial or number it may be accepted in commerce, but if it has a political, personal or commercial message it will not.
