A full-circle number is a number composed of sequential digits that reduces to the first digit of the sequence.

It is not a position name for a personal numerology chart. Instead "full-circle" is a characteristic of a number. Other characteristics numbers have are the characteristic "odd" or or the characteristic "even". Some numbers also have the characteristic "prime".

The number 1234 has the characteristic "full-circle" because:

• The digits the number is composed of are all sequential, and
• The number reduces to the first digit of the sequence ("1" in this case).

The link further above has more information about reducing numbers. In essence, you add the digits of the number together. If the result is more than 9, you add those digits together. Keep doing that until the result is a single digit.

To reduce 1234, this procedure is followed:

1+2+3+4=10
1+0=1

The reduced number for 1234 is 1, which is the same as the first digit of 1234. That's what makes it a full-circle number.

The number 89 is another full-circle number (8+9=17;1+7=8).

There is no special numerological meaning to a full-circle number that would not already be a meaning if it was not a full-circle number.

In other words, the fact of being a full-circle number has no special numerological significance.
