Python solution

# stores the modified string representation of a digit
digitStringDict = {
    " _ | ||_|" : "0",
    "     |  |" : "1",
    " _  _||_ " : "2",
    " _  _| _|" : "3",
    "   |_|  |" : "4",
    " _ |_  _|" : "5",
    " _ |_ |_|" : "6",
    " _   |  |" : "7",
    " _ |_||_|" : "8",
    " _ |_| _|" : "9"
}

# takes a multiline string as input
# outputs the int representation of that
def stringToAccountNumber(account: str) -> int:
    account = account.strip("\n")
    parts = account.split("\n") # split the actual string into three strings based on new-line character
    numberStr = "" # stores the string representation of the number

    for i in range(0,len(parts[0]),3):
        numberStr += digitStringDict[parts[0][i:i+3]+parts[1][i:i+3]+parts[2][i:i+3]]

    return int(numberStr)

Output,

test1 = '''
 _  _  _  _  _  _  _  _  _ 
|_| _| _||_||_ |_ |_||_||_|
|_||_  _||_| _||_| _||_| _|

'''

test2 = '''
    _  _     _  _  _  _  _ 
  | _| _||_||_ |_   ||_||_|
  ||_  _|  | _||_|  ||_| _|

'''

test3 = '''
 _  _  _  _  _  _  _  _  _ 
| | _| _|| ||_ |_   ||_||_|
|_||_  _||_| _||_|  ||_| _|

'''

print(stringToAccountNumber(test1)) # output -> 823856989
print(stringToAccountNumber(test2)) # output -> 123456789
print(stringToAccountNumber(test3)) # output -> 23056789
