In numerology, it depends on what the number is related to.

I did not see the number 143 in your numerology profile. Therefore, I'll assume the number is related to something else.

The significance and even the definition of a number depends on what the number is applied to, what it is that the number has an effect on.

A few examples:

Residence number. The number 143 applied to a residence number has little significance. The effect of a residence number on a person's life is tiny compared to some other numbers (like the person's name and birth date numbers). The number 143 as a residence number has to do with finances related to personal independence.

Name number. The number 143 as a name number has enormous significance. The number is reduced to the digit 8 (1+4+3=8). It brings group management, financial, and legal inclinations.

ID number. The number 143 as an ID number has a similar meaning to the residence number, but depending on what the id number applies to. If it applies to a school or university ID, it brings with it some tendencies to study finances or company management. If the number 143 applies to a government issued license to drive, it brings with it some tendencies to assert financial independence even when reality would indicate otherwise.

Those are a few. Perhaps they will help you determine the significance of the number 143 in your situation.
