Who certifies the results of any poll? Generally it is the polling agency itself, through conducting spot checks on accuracy. No government agency oversees poll results, so there is nothing to make them "official," with the exception of election polls.
Election polls are are not scientific polls, as they are not random samples of public opinion. Instead, everyone eligible to vote casts a ballot. Election polls are the only "official" polls.

A quality that is not characteristic of a scientific poll is bias in sample selection. Scientific polls aim for random sampling to ensure that the results are representative of the larger population. Other qualities include clearly defined questions, a sufficient sample size, and the use of statistical methods to analyze results. Bias undermines the validity and reliability of the poll's findings.
