SQL between clause returns rows for values outside bounds - sql

Question

As the title says when I use the sql between clause I am running it against an address range from low to high and I am putting in a number that is outside of the two and getting rows returned to me. And I would like to know why.

Quick hit on the query, I am using an address number of 4929 and getting rows returned to me where the address range low and high numbers are 400 and 498 respectively.
Here is the query:
SELECT
ZipCodeLow ,
ZipCodeHigh ,
ZipExtensionLow ,
EndingEffectiveDate ,
BeginningEffectiveDate ,
AddressRangeLow ,
AddressRangeHigh ,
StreetName ,
City ,
ZipCode ,
Zip4,
Zip4High
FROM BoundTable
WHERE
('68503' BETWEEN ZipCodeLow AND ZipCodeHigh) AND
('4929' BETWEEN [AddressRangeLow] AND [AddressRangeHigh]) AND
([StreetName] = '32ND') AND
(GETDATE() BETWEEN [BeginningEffectiveDate] AND [EndingEffectiveDate])

Answer 1

Convert 4929 to numeric first and then run the query:
SELECT
ZipCodeLow ,
ZipCodeHigh ,
ZipExtensionLow ,
EndingEffectiveDate ,
BeginningEffectiveDate ,
AddressRangeLow ,
AddressRangeHigh ,
StreetName ,
City ,
ZipCode ,
Zip4,
Zip4High
FROM BoundTable
WHERE
('68503' BETWEEN ZipCodeLow AND ZipCodeHigh) AND
(convert(numeric,'4929') BETWEEN [AddressRangeLow] AND [AddressRangeHigh]) AND
([StreetName] = '32ND') AND
(GETDATE() BETWEEN [BeginningEffectiveDate] AND [EndingEffectiveDate])
