The Meaning of Numbers: The Number 12
Twelve can be found in 187 places in the Bible. Revelation alone has 22 occurrences of the number. The meaning of 12, which is considered a perfect number, is that it symbolizes God's power and authority, as well as serving as a perfect governmental foundation. It can also symbolize completeness or the nation of Israel as a whole.
For example, Jacob (Israel) had twelve sons, each of which represented a tribe begun by a prince for 12 total. Ishmael, who was born to Abraham through Hagar, also had twelve princes.

Twelve thousand from each tribe of Israel (144,000 total) will receive salvation during the end time's Great Tribulation (Revelation 7).

Christ's bride in Revelation 12, the church, wears a crown containing twelve stars.
The New Jerusalem, which is made in heaven and brought to the earth by God himself, contains 12 gates made of pearl that are each manned by an angel. Over each gate will be one of the names of Israel's twelve tribes. The walls are 144 cubits high (12 multiplied by itself - Revelation 21:16 - 17), with the city itself being 12,000 furlongs square.

The Scripture's first recording of Jesus' words occurs when he is twelve years old (Luke 2:42).
The high priest's breastplate, also called the breastplate of decision, had 12 stones embedded in it. Each stone represented a tribe of Israel. The Urim and Thummim were part of the High Priest's breastplate. They were primarily used to consult God regarding important matters (1Samuel 28: 3 - 6, Numbers 27:21 and so on). Both the first century historian Josephus and the Talmud identify the Urim and Thummim with the breastplate stones.
Of all the numerals found in scripture, twelve, along with three, four, seven and ten, are unmistakably used in a symbolic fashion in God's word.
