FOR IMMEDIATE RELEASE


            NUMEREX REPORTS FOURTH QUARTER AND FULL YEAR 2003 RESULTS

                COMPANY STRENGTHENS ITS FINANCIAL POSITION AS IT
                      SUBSTANTIALLY NARROWS OPERATING LOSS

     CONTINUES WITH NEW PRODUCT LAUNCHES AND STRATEGIC MARKETING INITIATIVES

ATLANTA, FEBRUARY 23, 2004 - NUMEREX CORP. (NASDAQ: NMRX), today announced a net
loss of $400 thousand for the fourth quarter of 2003 and a full year net loss of
$1.4 million. Included in these results is the gain on the sale of Data1Source
LLC of $1.7 million that occurred in September 2003. These results compare to
net losses of $3.8 million and $7.7 million for the comparable periods of 2002,
including full year acquisition costs of $1.9 million. Fully diluted losses per
share were $0.04 for the quarter and $0.13 year-to-date. This compares to fully
diluted losses per share, including acquisition costs, of $0.35 and $0.71 for
the comparable periods of 2002. Net sales were $5.3 million for the quarter and
$20.2 million for 2003 in total compared to $3.9 million and $24.5 million for
the comparable periods of 2002. Please see the attached financial statements for
more details.

"2003 was a very busy year for the Company," said Stratton Nicolaides, chairman
and CEO of Numerex, "and the fourth quarter was no exception. In December, we
announced the release of IPContact(R) 8.0, a desktop videoconferencing software
package that boasts industry-leading performance levels with multi-point
capabilities. IPContact supplements the Company's PowerPlay(TM) suite of turnkey
videoconferencing hardware solutions. Our fourth quarter revenues included the
initial sales of IPContact and we believe that this software package will gain
further traction in 2004. Also, in December, we announced a strategic marketing
initiative with Niigata Seimitsu and Toyota Industries Corporation to
manufacture and distribute Numerex's extensive suite of product offerings,
including Uplink(SM), MobileGuardian(TM) and VendView(TM). We are very excited
to be allied with a company such as Niigata who are committed to providing
Numerex with exceptionally high quality manufacturing and assembly resources."

"We also continued to strengthen our financial position, and in January 2004, we
issued a $4.5 million convertible Term Note. The net proceeds from the financing
were used primarily for the repayment of the Company's remaining $3.5 million
short-term debt to Cingular Wireless and to provide additional working capital.
The Note is repayable in cash or, under certain circumstances, stock. During
2004, cash payments, if required, would be limited to just over $800,000,
including interest."

Other key initiatives undertaken in 2003 included:

- -    Launched the release of MobileGuardian(TM), a web-based vehicle location
     and recovery solution that combines the accuracy of Global Positioning
     System, or GPS, and Cellemetry(R)

- -    Completed the purchase of Cingular's 40% interest in Cellemetry LLC, a
     joint venture formed in 1998, giving Numerex full ownership of Cellemetry
     LLC and its subsidiary, Uplink Security Inc.

- -    Announced that Numerex's Australian subsidiary, DCX Systems, Inc., reached
     a five-year agreement with Telstra, a leading Australian
     telecommunications provider, to expand the availability of its Securitel
     service, a derived channel based alarm security service offered in
     Australia.

- -    Reached an exclusive agreement with the nations largest automotive
     dealership to market MobileGuardian(TM), providing point of sale access to
     over 400 dealership locations.

- -    Announced the sale of the our mobile messaging service bureau, Data1Source
     LLC, to Wireless Services Corporation, allowed us to focus our resources on
     growing our core wireless telemetry business.

- -    Added VendView(TM) to our wireless data solutions portfolio, a service
     providing remote monitoring of vending machines 24 hours a day, seven days
     a week, utilizing our Cellemetry(R) network for ubiquitous communications
     coverage throughout North America

                                   -continued-

"Our financial results for the fourth quarter of 2003 included a 37% increase in
revenues over the same period last year and we continued to focus on solid,
creditworthy customers. Compared to the prior quarter, after eliminating
revenues of $378,000 and $154,000, respectively, attributable to Data1Source
LLC, total revenues increased slightly. However, this overall comparison masks
the strong revenue performance of the Wireless Data Division, which recorded
sequential growth of over 17% after eliminating revenues attributable to
Data1Source LLC. Finally, with regard to liquidity, only the payment of
accumulated interest to Cingular and fees related to the Data1Source transaction
prevented the Company from adding to our cash balance reported at the end of
September 2003. Our focus in 2004 will be sound revenue growth, continued cost
control and aggressive cash management."

A complete analysis of our 2003 quarterly revenues by division is included in
this press release.
